So- to learn OOP I am building a C# console app where I take in MTA api data and see where subways are at and when they will arrive at my selected station.
I've started with creating a GTFSParser class - which I thought would server as an object to kinda clean up the data from the api. However, I am running into a logic issue. I can accomplish my goal by creating a bunch of different methods within this class - but doesn't this defeat OOP standards? How do you conceptualize what propertys to put in, whether to make it an abstract class, polymorphic or whatever?
